The Plant Collections Network (PCN) (formerly the North American Plant Collections Consortium) is a group of North American botanical gardens and arboreta that coordinates a continent-wide approach to plant germplasm preservation, and promotes excellence in plant collections management. [1] The program is administered by the American Public Gardens Association from its headquarters in Kennett Square, Pennsylvania, in collaboration with the USDA Agricultural Research Service.
Current objectives of the Plant Collections Network are to:
The network is intended to represent woody and herbaceous ornamentals, both native and exotic. The main objective for each network member is to assemble a comprehensive group of plants for a particular taxon, collecting plants from different populations throughout their natural range that are both taxonomically and genetically distinct.
Participating institutions maximize the potential value of their collections by making efficient use of available resources through a coordinated continent-wide approach, and strengthening their own collections through collaboration with others.
Criteria for participation in the Plant Collections Network are:
The accreditation process includes submitting a written application for each collection to be considered, then a peer site reviewer conducts an onsite assessment and submits a report with recommendations. [2]
As of March 2016, Network participants and Nationally Accredited Plant Collections included: [3]

The Seed Herbarium Image Project (SHIP), is an initiative of the Arnold Arboretum of Harvard University to create a web-based repository of high-resolution digital images documenting the morphology of woody plant seeds and selected fruit structures. Headquartered at the Arboretum’s Dana Greenhouse facility and coordinated and photographed by curatorial assistant Julie McIntosh Shapiro, the Seed Herbarium Image Project supports the work of educators and professionals in horticulture and the botanical sciences, particularly in conservation research and management of rare and endangered species. The digitized images of seeds offer an important new aid for teaching seed identification—a fundamental skill in plant propagation, hybridization, and distribution—and serve as a resource for nurserymen, horticulturists, botanical curators, taxonomists, ecologists, and the general public. SHIP also provides an online resource for botanical institutions and nurseries to verify their collections and inventories. SHIP is made possible through the generous support of the Stanley Smith Horticultural Trust, Cabot Family Charitable Trust, and the J. Frank Schmidt Family Charitable Foundation.
